Final answer:
The distance from a' to b' is 24 units.
Step-by-step explanation:
To find the distance from a' to b', we can use the concept of scale factors. In this case, the scale factor is 3. If the distance from a to b is 8 units, then the distance from a' to b' can be calculated by multiplying the scale factor by the distance from a to b.
The distance from a' to b' is equal to 3 times 8 units, which equals 24 units.
